Ratings and reviews

I really love this app. I bought the lifetime membership! The only thing that docked a star for me is that there is no dictionary :( other ePub/PDF readers have a dictionary feature where if you highlight a word you can save it in a "dictionary" folder, kind of how you can save "highlights" and "notes" in different folders. I hope that one day this app adds that. This app would be an automatic 5 stars if they ever add a dictionary!!

Aquile Reader is a fantastic all-in-one reading app. I love that it handles EPUBs, PDFs, comics, and manga in one place, and the Android/Windows sync makes it super convenient to pick up right where I left off. The customization options are great too, especially dark mode, font choices, and layout controls. Text-to-speech is a huge bonus when I want to listen instead of read. Smooth, easy to use, and a really solid Kindle alternative for anyone who wants more control over their library.

Amazing cross platform app! My only gripe: The syncing could definitely be better. I feel like it needs to be on focus loss or sleep rather than closing out of the book, (especially on windows) I've opened a book on another device far too many times and been tens of chapters behind.
